AKRON, Ohio (AP) — Officials say contractors started conducting controlled blasts underground in downtown Akron last week as part of work on the Ohio Canal Interceptor Tunnel.
The Akron Beacon Journal reports (http://bit.ly/2gfzoeZ ) the giant underground tunnel is a major component of the northeast Ohio city's massive $1 billion sewer project to limit overflows into local waterways.
Project officials say the use of explosives became necessary after workers got to the point where the underground rock was too hard to continue digging.
Blasting began Nov. 8 in one of the two shafts in the construction area along the Akron Innerbelt at West Market Street.
Residents within a half-mile radius of blast sites may potentially hear a sound similar to fireworks and feel vibrations when blasts are occurring.
